My favorite is the history of chili pepper. It's something so fundamental to indian cuisine that I assumed chillies were native to India for a long time. His video shows the true history of how that spice travelled from the Americas to all over the globe
Have you read Charles C. Mann's book "1493: Uncovering the New World Columbus Created"? It's all about the global impact of the opening of the New World by the Europeans, and how the global exchange created and is creating the "homogenocene", the age of homogeneity. There's a part about a folk song in the Philippines that lovingly goes over the crops being grown around a village. They're all introduced.
When my Korean friends tell me that my cuisine isn't spicy enough: Well... let's talk about that spice.
Potatoes, tomatoes, bell peppers, corn, sweet potatoes, pumpkins/zucchinis/most squashes, cassava, the common bean (including pinto, black, kidney, etc), cassava, sunflowers, avocado, etc all didn't exist in European kitchens until the 1500s (and not really widespread until at least the 1600s).
Also, most of these crops were specifically domesticated in the Andes. If you go to the Andes today you can still find traditional potato farmers who take care of hundreds of varieties of potatoes of all different shapes and colors. Some are ornamental, some are edible raw, some are only used in soup, some are even used medicinally
Maybe surprising is that there are no native species of banana to "the New World" despite there being about 100 species and thousands of named cultivars.
